so, so many possibilities. i'll list a few:
dryness/tear film deficiencies
allergies/gpc
corneal irritation/spk/and the like
blepharitis/meibomianitis/eyelid inflammation
way too vague of a complaint to be solved here. would need an eye examination to figure it out. not dangerous, but not diagnosable w/o someone actually looking at it
and to be more specific i feel very tired! can u please explain to me one of the each from the above ?
um, no. thats what an exam is for. thats what i'm telling you. too difficult to determine what you have from your description...cant narrow it down w/o seeing it. and no, sorry i dont have time to explain all those conditions to you here. google:
"superficial puntate keratitis"
"blepharitis"
"dry eye syndrome"
"giant papillary conjunctivitis"
that should get you started pretty well...
